Loss power at 3000-3500 rpm after remap Nissan 1.5 dci

Postby bobuzi » Sat May 25, 2019 6:01 pm

Hello forum! :)

I'm experiencing a power loss at 3250 rpm after remap (by local tuner) my Nissan 1.5 DCI.
The tuner still optimizing tha map, but I m courious if you can help me to diagnose this behavior.

As you can see in the imagne, also In stock map, at 3400 rpm, there is a small drop.
This drop is larger in the modified maps and at higher rpm.
I don't have all the details to share about tuner modified maps, but I have the original file.
However, could you give me your opinion: some faulty sensor or some torque limiter that has forgotten by tuner?

Or can it be considered "normal" behavior?

Thanks in advance
